Lying on a desk: Potential energy
Falling off a desk: Kinetic Energy
kinetic energy
turns into vibration and heat energy.

How about the sound it makes and the puff of air movement it creates.
Just about as much as it had potential energy before it started falling - since most of the potential energy will be converted into kinetic energy. The exact amount depends from how high it falls.
kinetic energy
A falling book in mid-air has what kind of energy?
A falling book exhibits a change from potential energy (rest) to kinetic energy (motion).
turns into vibration and heat energy.
When a book is falling from a bookshelf, it is in a state of kinetic energy because it is in motion. Potential energy arises when the book is stationary on the shelf due to its height above the ground.
when book is dropped from the height its kinetic goes on increasing and the sudden stop to the book when it touches the ground all the kinetic energy of the book is converted into potential energy of the book which helps the book to be stable after the impact, in short when the book hits the ground kinetic energy is converted to potential energy due to law conservation of energy.

There is no falling action in the book. the book jsut leaves you hanging
Yes

Yes it is. Because it has the POTENTIAL of falling off. Very simple physics, learned that in 6th grade.
